Well, good to know it's not just Linux.

One thing I noticed when I opened up the ADF on the 7450 is that there
are feed rollers on only the left side and none in the middle or on
the right.  It seems that this could easily lead to pages getting
twisted and jammed in the scanner.

I hope this isn't another case where HP outsourced and ended
up with an inferior product.  If I could get one of those old
indestructible HP ScanJet IIs or something with a big ADF I would
probably be happy.

Or maybe there just aren't any good scanners with ADFs out there?
That seems unlikely.

Thanks,
P.
